BodyAngularVelocity bug

So i have a central object welded to 4 other ones and it is deleting itself when i set it to infinite.
The only problem is it deletes itself when i run the game.

It is supposed to be a rotating Mesocyclone.

I know BodyMovers are deprecated

Why set it to infinite?
What’s keeping the cyclone from spinning off the map? If you don’t have something it’s going to act like a big unanchored spinning top.
